Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power conversion system, having unit power converters connected in parallel using DC circuits and AC circuits, capable of suppressing a vibrating current running through the DC circuits comprised of the connected unit power converters by switching the unit power converters connected in parallel, and zero-phase currents running through a ground circuit when the power converter transmits electric power to an AC system through a transformer with a neutral point grounded.SOLUTION: In the power conversion system, a gapped reactor is connected to each of a positive electrode and a negative electrode of a DC terminal of a unit power converter, and the unit power converter is connected to the other unit power converter through the reactor.
